FINISH-REMOVER.

No Drawing.

and relates especially to removers comprising cyclic. hydrocarbons containing GIL. groups and to the immediate derivatives'of such hydrocarbons, including their alcoholic,-

ketonic, aldehydic. or acetic derivatives.

Manyof the cyclic CH hydrocarbons and their derivatives are valuable as finish sol vents in removers such as the cyclic paralliu.-. including c \"clopcntane or pcutamethylene, vinyl trin'iethylene, subcrone or cyclohepta no. hexahydro benzenes or naphthenes embracing hexahydrobenzol, hcxahydrotoluol and the like. Many immediate derivatives of these cyclic paraffins or cyclic hydrocarlmm arealso desirable finish solvents, such. for example, as acetyltrimethylene. ditetramethylene ketone, adipin kct-one (lwtopentamethylene), methyl cyclopeutenon, cyclopentane carboxylic acids, suberone, cyclohexanol, pimelin' kctone, hexahydrometatoluic acid and similar carboxylic acids of the hydroaromatic group and other oxygenated or halogenated bodies thereof. Penetrating finish solvent material, that is, solvents having a generally benzolic character oraction in removers may be used in such removers, including benzol, toluol, Xylol, cumene, the somewhat similar pctroleum products, benzin, gasolenc, and so forth, andalso carbon-bisulfid, carbon-tet rachlorid, acetylene chlorid and other chlorinated compounds. Loosening finish solvent .material, that is, solvents having a generally alcoholic character or action in removers may also be used in the remover when desired, such as the strict alcohols, methyl, ethyl, propyl, butyl and benzyl alcohols, for instance, in their cheaper commercial forms when desired, including de natured alcohol and also other solvents of a. generally alcoholic character, such as methyl acetone, acetone, au d other lietones, acetone oil, resin oil and so tt'ortluas well as various derivatives thereof, such as amyl acetate. Although notnecessary in-all cases, suitable stiffening material may be employed in the Specification of Letters Patent.

Application filed May 27, 1907. Serial No. 375,901.

remover, such as wood flour, starch, whiting,

waxy bodies, such as ceresin, paraflin, beeswax, ozocerite, oleic and other fatty acids,.

and nitrocellulose, many of which form effective evaporation retarding films over the exposed surface of the remover when in use. The various ingredients of the remover are preferably thoroughly incorporated by agitation at a suitable gentle heat, the stiffening material when of a soapy or waxy character being preferably first dissolved in' the more energetic solvent material therefor, although this is not necessary in all cases.

A suitable illustrative remover of this type may comprise benzol 12 gallons, commercial hexahydrobenzene 27 gallons, com mercial adipin ketone 43 gallons, wood flour 50 pounds and paraffin or ceresin wax 30 pounds. Another illustrative remover may comprise light naphthcne oil gallons, adi-, pin ketone 60 gallons and suberon'eb 'gallons. Another illustrative remover may comprise naphthene oil 50 gallons and adipin ketone gallons; and still another illustrative remover may comprise hexahydrobenzene which may be in its commercial form gallons, acetone 25 gallons and paraffin or ce'rcsin wax 10 pounds.

Having described this invention in connection with a number of illustrative ingredients and formulas, to the details ofwhich disclosure it is not, of course, to be limited, whatis claimed is:

1. The finish remover comprising approximately benzol 12 gallons, commercial hexahydrobenzcne 27 gallons, commercial a-dipin ketone 43 gallons, wood flour 50 pounds and paraffin wax 30 pounds.

2. The finish remover comprising approximately benzol, commercial hexahydrobenzene 27 gallons, adipin ketone 43 gallons and waxy stifiTening material.

3. The finish remover comprising hexalrvdrobenzenc, adipin ketone and stiffening material.

4. The. finish remover comprising ad pin ketone and stiffening material.

5. The finish remover comprising composite finish solventmaterial including adipin'ketone.

6. The finish remover comprising composite finish solvent material including hexahydrobenzene and adipin ketone.

7. The finish remover comprising coiu BEST AVAILABLE COPY Patented Aug. 15,. 1911.

posite finish solvent material including a liquid, finish solvent, ketonic derivative of a cyclic CH hydrocarbon.

8. The finish remover comprising a composite solvent material including a liquid, finish solvent, ketonic derivative of a cyclic OH, hydrocarbon and Waxy stiffening material.

9. The finish remover comprising a composite finish solvent material including a liquid, finish solvent, ketonic derivative of a cyclic CH hydrocarbon.

10. The fii'iish remover comprising a composite solvent material including a liquid, finish solvent, oxygenated cylic CH, hydrocarbon.

11. The finish remover comprising composite finish solvent material including a liquid, finish solvent, ketonic derivative of -a cyclic CH hydrocarbon and miscible solvent material of a generally penetrating and loosening character.

- material including 12. Ihe finish remover consisting substantially of composite volatile finish solvent finish solvent liquid lgetonic derivatives of cyclic CH hydrocarons.

13. The finish remover comprising hexahydrobenzene and miscible loosening finish solvent.

M. The finisfi remover comprising hexahydrobenzene, miscible finish solvent material and stiffening material.

15. The finish remover comprising ketonic cyclic CH hydrocarbon finish solvent and loosening finish solvent material.

16. The finish remover comprising cyclic CH hydrocarbon finish solvent material and adipin ketone.-
